HEALTH ASPECTS OF KARATE AS PHYSICAL EDUCATION AND EXTRACURRICULAR ACTIVITY

The present study examined energy expenditure, metabolic equivalent (MET) intensities of karate exercises for health promotion, and bone properties of karate practitioners to examine the health aspects of karate as physical education and an extracurricular activity. The mean energy expenditure following a 70-minute karate practice was 563 kcal for men and 268 kcal for women. The calculated mean MET intensities resulting from the 70-minute karate practice were 7.9 METs for men and 5.2 METs for women. The mean MET intensities of all exercises for men and women were above 3 METs which is defined as “active physical activity” in the “Physical Activity Reference for Health Promotion 2013” in Japan. Practicing karate, especially sparring techniques, may help to enhance bone mineral density. It appears that longer duration, higher frequency, and earlier start of physical training positively influenced skeletal status.  Article visualizations

大学生活への期待と現実及び生活習慣が大学生活への適応に及ぼす影響

The purpose of this study is to clarify the relationship between expectations for university life and career paths. The subjects of the survey were first-year university students, and 504 respondents were obtained. The contents of the survey were to set up adaptation to university life and lifestyle habits. Corresponding t-tests were conducted at the time of admission and after admission. Lifestyle habits tend to deteriorate after enrollment. The result was that there was a large gap between the expectations and the reality of university life due to the time and events. Subsequently, a hierarchical multiple regression analysis was conducted, and it was found that the adaptation to university life was influenced not only by the image of university life but also by lifestyle habits. In the future, it will be necessary to change the image of university life before entering the university and to maintain good lifestyle habits.本研究の目的は，大学生活への期待と進路との関係を明らかにすることである。調査対象は， 大学１年生であり，504名の回答を得た。調査内容として，大学生活への適応と生活習慣を設定した。入学時と入学後の対応あるt検定を行った。 生活習慣は，入学後悪化している傾向がある。大学生活への期待と現実は，時間的ゆとり及び行事へのギャップが大きい結果であった。その後，階層的重回 帰分析を行い，大学生活への適応には，大学生活へのイメージのみではなく，生活習慣による影響が認められた。 今後，入学前の大学生活へのイメージ変化や良い生活習慣の維持が課題である
